On Saturday, 17th of June the Dutch Puzzle Association will organise the Open Dutch Sudoku and Puzzle Championships 2017, together with ORTEC, a consulting firm in Zoetermeer. The ORTEC-office opens its doors on this day to host the event.

Participation is also open for international players, so if you want to compete you are more than welcome!

The championships are organised in such a way that you can participate in both puzzling and sudoku on the same day.

Also volunteers are welcome to help correcting or other tasks that come with such an event.
